New Zealand adverse event reporting for medical devices

1. Key takeaways

State the most important fact first: adverse event reporting for medical devices in New Zealand operates on a voluntary basis — it is not a statutory duty. The Medsafe page states in its own words: “Medsafe operates a voluntary scheme for medical device adverse event reporting.” (https://www.medsafe.govt.nz/regulatory/DevicesNew/9AdverseEvent.asp, Revised: 19 March 2020.)

The contrast with medicines is stark. Section 41 of the Medicines Act 1981 (1981 No 118) requires the New Zealand importer or manufacturer of a medicine to notify the Director-General immediately once there is reason to believe use has produced a major adverse effect, whether in New Zealand or overseas; breach attracts up to NZ$1,000 under s 41(2). That is a statutory duty. The Act contains no device counterpart, and neither do the 1984 or 2003 Regulations.

Two conclusions follow. First, for the Sponsor (New Zealand sponsor), the timelines Medsafe recommends — 10 calendar days, 10 working days and 120 calendar days — are all recommendations with no legal basis, marked throughout as practical estimates. Second, more important: voluntary does not mean optional — the system should still be built to statutory-grade specifications, for the reasons set out below.

2. Legal basis

The table below lists the sources relied on, separating the voluntary reporting framework administered by Medsafe from the statutory provisions that supply the real enforcement pressure.

3. Expert insights

Insight 1: whether to report is decided by three criteria. Medsafe requires all three for a reportable device event: (1) an event has occurred — malfunction or performance deterioration, an unexpected or out-of-specification outcome, inaccurate labelling, IFU or promotional material (including omissions and defects), a serious public health threat, or use error; (2) the event is associated with an identified device; (3) the event has led to, or could lead to, injury. Any one missing, it is not a reportable device adverse event.

Insight 2: serious injury has three defined standards. A life-threatening situation; permanent impairment of a body function or permanent damage to a body structure; and the requirement for medical or surgical intervention to prevent permanent impairment or damage. This definition determines the branching of the reporting route and its urgency, and whether Medsafe may later ask for the outcome of the follow-up investigation.

Insight 3: eight categories are expressly non-reportable. Medsafe’s exclusion list covers: deficiencies the user can detect before use; events caused by the patient’s own condition; events arising solely from expiry of service life or shelf life where the failure mode is not abnormal; correct operation of a fail-safe device; events already described in a recall, product correction or hazard alert; events due to improper use, maintenance or device damage; and foreseeable events adequately described in the IFU. The list reduces noise — and is the first internal filter for whether to open a case.

Insight 4: if it is voluntary, why build it to statutory grade? This is the core judgement of this article. First, voluntary means only that non-reporting carries no fine — not that there are no consequences when something goes wrong. Section 38 of the Medicines Act 1981 gives the Director-General the safety switch requiring evidence within 45 days where a device may be unsafe, and selling before the requirement is met is an offence under s 38(8) carrying up to 6 months imprisonment or a NZ$5,000 fine — and the adverse event log is a core component of that evidence. Second, reg 50 of the 1984 Regulations allows the Director-General to order withdrawal and require disposal or destruction; once an order issues, refusal to cooperate triggers reg 64(1)(b) with a cap of NZ$500, and without a complete event log even the required how-and-when statement cannot be drafted. Third, under s 80 strict liability the defence must prove all reasonable steps, with written notice within 7 days of the summons — a continuously operating collection and assessment record is the most economical form of that evidence. Fourth, s 79 principal liability pulls the line through to directors and managers personally.

In one sentence: New Zealand trades voluntary reporting for cooperation, while retaining the full regulatory weight through the s 38 evidence duty, reg 50 recall orders and strict liability. Building the voluntary mechanism to statutory specifications is the lowest-cost option within this regime.

4. Practical recommendations

• Adopt Medsafe’s three recommended timelines verbatim as internally mandatory timelines, marked as practical estimates rather than statutory periods: death or serious injury — initial report as soon as possible and no later than 10 calendar days, final report after the investigation; minor injury (where a market action may result) — initial 10 working days, final 120 calendar days; quality problems by analogy.
• GRZAN’s approach when building a vigilance system is to compress the three criteria, the three serious injury standards and the eight exclusions into a single-page decision flowchart at the first complaint-handling station — pushing the report-or-not dispute down to the operating layer while leaving a traceable decision record.
• Distinguish the channel by submitter: the Sponsor uses the Industry form; healthcare institutions the Healthcare Professional form; patients the Consumer form; the single mailbox is devices@health.govt.nz. GRZAN recommends one internal window for external submission, so the same event is not filed twice.
• Establish a three-way link between the event log, WAND records and distribution records (device name + GMDN code + batch or serial number); in a s 38 scenario, whether a batch’s full destinations and related events can be pulled within 45 days decides whether the evidence stands.
• Keep a written justification every time an exclusion is applied — in a voluntary system the hardest failure mode is not the missed report but the non-report no one can explain.
• Link adverse event trending to the recall grading assessment in article 42: once a trend points to a common design defect, start the grading assessment immediately and consult Medsafe before initiating.

5. Verification checklist

• □ Do internal documents state that device adverse event reporting in New Zealand is voluntary, and avoid describing it as a statutory duty?
• □ Are the three timelines — 10 calendar days (initial, death/serious injury), 10 working days (initial, minor injury), 120 calendar days (final, minor injury) — in the procedure and marked as practical estimates?
• □ Has the three-criteria test (event occurred / associated with an identified device / has led to or could lead to injury) been made into a decision flowchart?
• □ Can staff apply the three serious injury standards (life threat / permanent impairment or structural damage / intervention to prevent permanent damage) fluently?
• □ Is the 8-category exclusion list printed in the operating manual, with a written justification for every application?
• □ Are the use cases of the Industry / Healthcare Professional / Consumer form sets defined, with one submission outlet at devices@health.govt.nz?
• □ Can the event log be linked three ways to WAND records and distribution records by batch or serial number?
• □ Is it known that the real statutory pressure comes from s 38 (45-day duty; selling in breach carries up to NZ$5,000 or 6 months imprisonment) and reg 50 orders (breach up to NZ$500)?
• □ Is adverse event trending linked to recall grading assessment, with Medsafe consulted before any recall is initiated?
